I slotted all my human boffs to see the effect of the fix. The obvious benefit so far is that getting VM'd by a D'drex without ET1 isn't as annoying any more.
However, I've yet to notice the bonus to Starship Hull Repair. I have 100 in that stat and slotted the 5 boffs, but HE1 still heals for crap on my Defiant. (I have 41 aux power after counting all my stats and gear bonuses) Its not reflected on the space stats either.
I'm new to the game and am trying to figure this stuff out on my own. I swapped to all human officers with Leadership space passive last nite. Each officer increased subsystem repair by +20 each. With 5 humans i got +100 to subsystem repair. My total is now 184. My hull regen was 279.4%/min.
